I have never experienced the error "Couldn't find IOSurfaceRootUserCleint for task" before but in the verbose log, the prelinked kernel has expired, you can try rebuilding it by booting in Single user mode
boot with kernel flag -s
#Run the following commands one by one
mount -uw /
kextcache -i /
reboot
Let me know the results

First problem - After playing a video on any player, only the sound is played and the picture will not be displayed. I tried different settings with VLC but the image is still not.
The second problem - In Safari is scrolling OK, in Chrome the image is jerking for scrolling.
Default is Sierra after installing with HD 7000, does not help changing to HD 630
Is there anything else to do with the graphics card ?
I have already written in the forum but no one can help me. Help me please.

Hi guys, managed to make a hackintosh and everything is going great (Wifi, cpu ECT)
But it's pretty damn slow, i tried one of my favorite lightweight games to test (The Ultimate Doom) and it could barely run THAT! This is my first time and i have no idea how to get my 8570 to work.. Probably should have read a bit, eh? Lol.
And no I don't plan on using my hackintosh for gaming, but god so slow..
Thanks, help would be very appreciated.
Edit: It's the dedicated version btw, and in about my mac I see "Graphics Display 3 MB" maybe the issue?

Trying to boot to the installer but I get instant reboot after the following:
I am using the following flag (I tried a variation - I need USBBusFix=Yes otherwise it fails even earlier):
All my USB devices turn off just before it reboots, so I'm guessing it loses connection to the USB install media - but I can't work out why it's disabling all the USB's.

Hi guys. Well, this is my second day of troubles, I touched everything, I installed max like 5 times in the same day, trying to figure out things and well.
My Mac it display my graphic card on the #About this Mac tab With 2047MB ( So I guess all is right ) I installed the latest nvida drivers and on clover I activated the NvidaWeb.
The problem is the resolution.
Max resolution allowed is 1280 x 1024 and 800 x 600.
I used to boot with nvd_drv 1 with nvd dry 0, I used to boot with all that things, and without them.
BUT No way to fix the resolution.
Someone knows what-s going wrong and how can I fix it?
Bdw im using iMac14,2 and OS X Sierra 10.12.3
Im connecting to the screen with DVI adapter. ( Maybe that causes the problem ) But it shows Im running 2047 MB so... idk why I can't change resolution.
Thanks!
=================================
SOLVED EDIT: Hi guys, in Display Resolution, I just set it in "Default for display" and after that pressing "THE WINDOWS BUTTON KEY, IN MY CASE, IDK WHAT KEY IS THAT IN MAC KEYBOARD, I THINK THE CONTROL ONE OR IDK" PRESSING that key I selected Scaled, and it appears more options and resolutions.
There is a video on youtube about that called "Mac OS X Display Resolution" If someone has the same trouble.

So far I have installed Mavericks and then Yosemite on a DG31PR board. Everything is working great. But I am having trouble creating the Sierra install USB. I have tried 2 different Hackintosh without any luck. But, I will keep at it. Very happy otherwise, thanks.

Ok, so I built a new hackintosh with Niresh Mavericks 10.9.0 on a modified Dell Precision T7400 and mostly everything seems to be working correctly except for two things: Sound (The obvious one), and Online video content (Youtube, Facebook videos, etc) play at lower than 1 fps, frozen speed, after 10 seconds of playback it reaches 4 seconds of elapsed time and I have found no other forums explaining this or talking about this so I decided to bring it up here. As for the sound situation, I already bought a new card to replace the X-FI, so yes, I am aware of the Sound Blaster Audigy X-FI Xtreme Audio not being supported, but what caught my attention is that the sound was working and video playback problem was gone temporarily, I happened to hear the sound from my headphones sitting on my desk and put them on, and sound. I decided to test a video on youtube, the problem with the videos, gone. But after a reboot, they were back. However I have the logs from today and can give them to whoever wants/needs them to figure out what may have caused the sound to kick in on the X-FI and maybe add support for this sound card. I copied as far back in the time that the system was on while sound was working that I could up to the shutdown event. I know it's pretty large but I am not sure where to look, I am simply handing this out to whoever wants to see what may have given me audio on this card for the session. From what I can see that looked to be the most closely related to my issue is something to do with bluetooth (I don't have bluetooth, btw), it says in console: "9/20/17 6:49:55.785 PM com.apple.audio.DriverHelper[200]: The plug-in named BluetoothAudioPlugIn.driver requires extending the sandbox for the mach service named com.apple.bluetoothaudiod." repeatedly many times. This could be completely unrelated.
The only recent actions I made that I personally can think of that may have triggered this would be:
I installed several different versions of a music player through Winebottler and it failed to start, more and likely because of the lack of .net framework 2.0 and 4.0, this is my highest suspicion of being the likeliest cause, but I could be wrong.
I installed Crossover and installed the music player in it, which it ran in and is where I discovered that you need .net 2.0 and 4.0 (It had the player in it's database and installed .net automatically)
Ran Discord (It uses output/input, so may as well add that in)
The player was MusicBee, and when it crashed, it also left a log that I could probably try to reproduce if needed.
